His instructor should have spent more time with him at towered fields. You can hear the controller's frustration. He's obviously inexperienced so I don't want to bash him too much, but perhaps this clip can be used for other students as an example of what not to do.

I guess cases like these are the reason why you're required to do an oral exam on radio phraseology and procedures before being allowed to fly solo cross country in Germany.. Not saying it's a good test (just one more way to squeeze some extra money out of you) or that you're an ace on the radios afterwards but in this particular case, it would probably actually have helped...
